Study Notes

Natural Disasters

Types of Natural Disasters

  • Tectonic Disasters:
    • Earthquakes: sudden release of energy in the Earth's crust, causing seismic waves
    • Volcanic eruptions: eruption of hot ash, gas, and rock from a volcano
    • Tsunamis: large ocean waves caused by earthquakes, landslides, or volcanic eruptions
  • Hydro-Meteorological Disasters:
    • Floods: overflow of water that submerges land and affects human settlements
    • Landslides: movement of rock, soil, or debris down a slope
    • Droughts: prolonged shortage of water in a region
    • Hurricanes/Typhoons: strong, rotating storm systems that form over warm ocean waters
    • Tornadoes: rotating columns of air that touch the ground, causing damage
  • Climatological Disasters:
    • Heatwaves: prolonged periods of abnormally high temperatures
    • Coldwaves: prolonged periods of abnormally low temperatures
  • Biological Disasters:
    • Epidemics: widespread outbreak of a disease
    • Pandemics: global outbreak of a disease

Causes of Natural Disasters

  • Tectonic Plate Movement: movement of the Earth's crust, causing earthquakes, volcanic eruptions, and tsunamis
  • Weather Patterns: unusual weather patterns, such as high pressure systems, low pressure systems, and wind patterns
  • Climate Change: changes in global temperatures and precipitation patterns, leading to increased frequency and severity of natural disasters
  • Human Activities: deforestation, land degradation, and pollution, which can contribute to natural disasters

Effects of Natural Disasters

  • Human Impact: loss of life, injury, displacement, and psychological trauma
  • Environmental Impact: damage to ecosystems, loss of biodiversity, and pollution
  • Economic Impact: damage to infrastructure, loss of property, and disruption of economic activities
  • Social Impact: disruption of social structures, loss of community, and cultural heritage

Mitigation and Response Strategies

  • Early Warning Systems: detection and alert systems to warn people of impending natural disasters
  • Evacuation and Shelter: safe zones and evacuation routes to protect people from natural disasters
  • Infrastructure Design: designing buildings, bridges, and other infrastructure to withstand natural disasters
  • Disaster Relief: provision of aid, food, shelter, and medical care to affected communities
  • Recovery and Reconstruction: rebuilding and restoring affected communities and infrastructure
